I recently started to get an issue with my Heos AVR that is connected to a Yamaha subwoofer. All of the sudden the subwoofer stopped working. The only way to make it work again is to go into the Heos app and disable/enable the subwoofer from the app. After that is working for a few days and then it stops working again. I have already tried changing the cable and try with a different sub, but the issue is still there. I called Denon support and they suspect it is a software bug. Anyone else experience something similar?
